Statoil ASA and its partners have chosen a concept for the first development phase of Johan Sverdrup field on North Sea’s Norwegian shelf. It will be a field center consisting of four installations and power from shore, the company reported.
The proposed field center will lie about 90 miles west of Stavanger in nearly 400 ft of water. The reservoir depth is 6,200 ft.
The company announcement said the gross capacity of this phase is 315,000-380,000 boe/d. Oil will be transported to shore by dedicated pipelines to the Mongstad terminal in Hordaland county, Norway. Gas will move via Statpipe to the Karsto processing plant on Norway’s southwest coast.
In the first phase, the field center will consist of a process platform, drilling platform, riser platform, and living quarters. It will be powered by a transformer in the Karsto, delivering a direct current of about 80 Mw to the riser platform. The design leaves room for future development and alternative power options will be considered in subsequent phases.
Production will begin in 2019 with a field production horizon beyond 2050, said Statoil.
